first embodiment

[0029]the grommet of the present invention will now be described with regard to the present invention in reference to FIGS. 1(a) and 1(b). As shown in FIG. 1(a) and FIG. 1(b), a grommet 10a includes wire harness holding areas 11 and 12 which tightly engage and hold the outer periphery of a wire harness. An engagement area 13 is provided to fixedly engage with an installation opening provided in a vehicle panel. A tapered area 14 having a near-conical tapered shape over a full periphery thereof extends between the wire harness holding area 11 and the engagement area 13, and plurality of spaced linear convex areas 15a are provided to extend from an engagement area 13 side toward a wire harness holding area side over the entire periphery of the tapered area 14, that is, in an inserted direction of the grommet.

[0030]The linear convex surfaces 15a are integrally formed with the grommet from the same material as that of the grommet, which is achieved by utilizing a machining process to fo...

Abstract

The present invention relates to a grommet capable of easy installation by reducing an insertion resistance when conducting an insertion of the grommet into an opening of a vehicle panel. The configuration of the grommet allows molds for forming the grommet to have reduced processing costs, and molding and installation time can also be decreased. The grommet includes wire harness holding areas for tightly engaging around the periphery of the wire harness and an engagement area which fixedly engages an opening provided on a vehicle panel. A tapered area connects a wire harness holding area and an engagement area with a near-conical tapered surface extending over the outer surface of a tapered area, and a plurality of linear convex areas are provided to extend from a wire harness holding area to the engagement area, in an insertion direction of the grommet over the entire periphery on the tapered area.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a grommet which holds a wire harness having a route that penetrates an opening in a panel, particularly an opening in a vehicle panel, etc.[0003]2. Description of Background Information[0004]Wire harness arrangement routes for vehicles have recently become more complicated and versatile as mounting of various electrical components on vehicles advances. This requires a wide use of parts for wire harness protection or maintenance, such as harness protectors for avoiding interference with peripheral parts and grommets used for penetrating through the openings provided in a vehicle panel.[0005]In particular, via an opening which is formed in a vehicle panel, a grommet formed of integrally molded rubber, etc. is generally used on a wire harness having a route, for instance, from an engine compartment to a passenger compartment or from a vehicle body to door areas, for the purpose of holding a...
